+/// A simple class to make throughput and latency analysis.
+/**
+ *
+ * Keep the relevant information to perform throughput and latency
+ * analysis, including:
+ * -# Minimum, Average and Maximum latency
+ * -# Jitter for the latency
+ * -# Linear regression for throughput
+ * -# Accumulate results from several samples to obtain aggregated
+ *    results, across several threads or experiments.
+ *
+ * @todo The idea behind this class was to use linear regression to
+ *       determine if the throughput was linear or exhibited jitter.
+ *       Unfortunately it never worked quite right, so only average
+ *       throughput is computed.
